ALFRED FAVOLA, OF NEVI YORK, N. Y.

l WINDOW Loon AND GUARD.

Application filed September 20, 1921. Serial No. 502,006.

To all fio/tom t may concern: K

Be it lrnown that Anrnnn FAVOLA, a citizen of Finland, and a resident of New 'orlr, in the county of 1lflew York andState of l ew crk, have invented certain new and useful improvements in ai/Vindow Lock and Guard, of which the following is a full, clear, and exact specification.

This invention relates to a classof devices adapted to bc used especiallyv in conjunction with easement windows.

My invention has for its object primarily to provide a locli and guard designed to be employed for releasably locking the sashes particularly of Casement windows when swung to closed positions in the frames, and which is of a form serving to prevent rain from flowing through the space under the. closed windows during inclement weather. This is accomplished mainly by providing on the base member of the window frame a locking element and guard for being moved upwardly and downwardly into and out of the grooves of the sashes when closed in the frame to releasably lock the sashes and close the space between the lower edges of the sashesand base member so that rain and the like will be obstructed from flowing therethrough.

Another obj ect of the invention is to provide mechanism which is manually operable for operating the locking element and guard; and a further object of the inventionl is to 'provide a window lock and guard of a simple, efficient and durable construction which may be made of any suitable material in appropriate sizes.

With these and other objects in view, the invention will be hereinafter more fully described with reference to the accompanying drawings forming a part of this specification in which similar characters of ref# crence indicate corresponding parts in all the views. `and will then be pointed out in the claims at the end of the description.

In the drawings Figure 1 is a fragmentary detail sectional view showing a top plan of one form of my improved lock and guard applied to a casernent window, the view being talren on the line 1-1iof Fig. 2.

Fig. 10 is an enlarged fragmentary View showing a perspective of the locking element used in the device,.and

Fig. 11 is an enlarged rear elevation of` the operative mechanism used in theimodified form of the device. I

The device has a locking element and guard 10 which is karranged on the base member 11 between the stiles 12 and 13 ofthe frame 1li of a window 15 of a class commonly known asa Casement window constructed usually withtwo sashes, as 1 6 and 1 7, which are hinged, at 18, 18a, and 19, 19a, to the stiles 12 and 13 for adaptingthem to be swung inwardly and outwardlyiof` the frame to open and closed positions. In such easement windows it is customary to provide in the hinged edges of the sashes ver tical grooves, as 2O and 21, andon the op` posed faces of the Stiles 12 and 13 of the frame la may be fixed protruding weather strips, as 22 and 23, for being received in the grooves 2() and 2l when the sash'es are closed in the frame. Inl practicing my in'- vention I provide in the lower edges of the sashes normally alined grooves 24: and 25 which are Vin opposed relation to the base member 11 of the frame lll'of the window for reception of the lockingelement andv guard 10.

This locking element and' guard may be of. any suitable form', though the element shown is composed of cooperating strips, as 26 and 27, which are operably arranged on the base member ll of the frame le, and these strips are oitl suoli lengths as to embrace the space between the l? and ll or the window iframe. nifhe s tially l shaped in cross the flange 28 on the upper tace o11 member ll so that it will be under the lower tionary to the trame in a manner A the flange 29 oit the L-shaped strip protrude upwardly in snaced pron' nity the edge oi the bar S0 at the outside ot the window. rThe sashes 1G and li" oit the window are hinged to the traine lil 'tor being swung inwardly ano outwardly of the trame to and from above the bar 30 so that the grooves 2l and 25 of the sashes will be approximately above the liange off the stationary strip 2G, and t io upper free edge ol the iange 29 or the stationary strip is bent over in the fashion o. an inverted ll, as at 3l. Thestrip 27 of the looting lement and guard l0 is bent lengthwise in th shape or" an inverted ll to provide two sozio-ed flanges, as 32, 33, and a spanning member 84. The lower ree edge of the tls-nge 33 or thestrip 27 is also bent inwardly between the flanges 32 and 33 in substantially a shape, as at 35. The strip E27 as thus termed disposed in straddle arrangement over the inverted uJ-shaped part 31 ot the strip 26 so that the inner leg of the Ushaped part interts, as shown, in the lll-shaped part 3i or" the strip 26, and the strip 2? is ot Vsuch a size that it is adapted to be 'freely moved transversely upwardly and downwardly on the stationary strip :26. The strip 2T is also of such thickness that its spanningY member Se and adjacent parts of its llanges and 33 be moved into and ont ot the grooves E24 and 25 oit thc sashes 16 and 17 of the window when the sashes are closed in the trame lll, in order to releasably lock the sashes and to serve as a guard by closing the space between the sashes and the sill ll tor obstructing the passage windj rain and snow during)r inclement weather'. rlhe 'locking` element and guard l0 may be moved to locked and unlocked positions by manually operative mechanism, as 36 Figs, l` Q, 3, 5, 6, or by manually operative mecha nism, as 37 Figs. 7, 8, 9, il.

rlhe mechanism 36 has two spaced studs or short shafts 38 and 39 which journal-ed in spaced parallel relation` in the central part crosswise of the bar 30 ot the window trame 14 so that one or the ends ot each stud is in close proximity to the adjustable strip oi the locking element 70, studs are oi such lengths that both or. ends protrm;n beyond the opp: sii e f f oi bar 50 of the frame ends ot ment l0 rotatably alla heads, as l and of the ends oi l2 whieh tions lena' eular in shape7 outer periph-aries orV the bars are substanti t slots when leing swung; int

to s the treo end portions ot upv and downwardly which will move the strip oi' the loclrir ment l0 likewise in upward and directions into and out of the and 25 of the sashes i6 and l in the window traine outerends the stur meshing` gears or pi ions, aL and protruding from one oii'i crank handlea as which v: swung rotatably will cause 5l and the studs and to opposite directionsi The pins the studs will then be lilreii V- slots t8 ard ot the heads fmom- 2i" et the looking element l0 o unlock the window sashes, as above plained.

The mechanism 3? includes studs o3, 54 and bars 55, 5G which preferably sinrlar in :torni as well as being correspondingly enr @D ployed to operate the strip 27 or" Jrhe locking element l0 as the studs 38, 39 and the bar 43 of the mechanism 36. @n the ends the Studs and 54- opposite to the bars and 56 are two spaced gears or pinions l i and 58 Sonie ot' the teeth of these gears are cutaway or removed to provide recesses 59 and GO which are in register when the gears and studs 53 and are normally at rest To the central parts of the studs 53 and flvmay be held the ends of a spring, as Gl, having' its ends convoluted in encircling' fashion upon the studs, while the central part ot the spring' spans the studs. This spring is tensioned for normally serving to msm l Si t) revolvably holo the studs 53, 54E and the bars 56 in directions whereby the strip 27 of the locking element 10 will be yieldingly held normally in a lowered or unlocked position on the base member ll of the window frame Lt and so that the recesses 59 and 60 f the gears 57 and 58 are in register. On one of the sashes of the window is mounted bar or rod as 62, which is movable in upward and downward directions so that its lower end will pass into and out of the space between the gears 57, and 58. Projecting in opposite lateral directionsfrom theY lower end part of this bar are two rows of teeth, as and 64, and between the teeth at the lower ends of these rows are two lugs, as 65 and G6, of sizes and shapes to adapt them toV be movably inserted in the recesses 59 and 80 of the gears 57 and 58. `When the window sashes are unlocked and swung open the har 62 is normally positioned to extend below its sash so that its lower toothed end will pass into the space between the gears 5T and 58 with the lugs 65 and 66 being movably seated in the recesses 59 and 60. On the central part of the window sash carrying the toothed bar 62 may be a device, as 67, of a commonlv used type having a casing 68 formed of a plate 69 on one face of which is a protruding flange 70 with verticallv disposed spaced parallel side walls 71, 72 and having curved end walls 7 3, 74:.' in the central partv of the plate 69 is a rotatable stud shaft 75 of a length so that it protrudes into and exteriorly of the casing 68. On the outer end of the stud shaft is a handle 76, and on the end of the shaft interiorly of the casing is held a circular disk 77. Within the upper and lower parts of the casing are spaced slides 78, 79 which are movable toward and from each other to and from the ends of the casings. The opposed ends of these'slides are pivoted, respectively at 80, Si, to opposite parts of the disk 77 diametrically to its center, and to the second end of the lower slide is pivoted, at 82, the upper end of the toothed bar 62. When the sashes are closed in the frame the toothed bar will be moved into engagement with theV gears 57, 58, as shown in Figs. 7 and 8, and when the handle 76 is swung accordingly the rotation of the shaft 75 will partly rotate the disk 77 to move the slides 78, 79 for causing the toothed bar 62 to move downwardly. The gears 57,158 and the studs 53, 54 will then he revolved sufficiently to swing the bars 55, 56 upwardly which in turn will move the strip 27 of the locking element 10 into the grooves 2t, 25 of the sashes 16, 17. The sashes will then be releasably locked in the frame, and the space under the sashes will be closed against the passage of wind, rain and snow during inclement weather.
